Physics and Pathophysiology of the Airway
Learning Objectives
Explain the physical principles governing laminar and turbulent airflow in pediatric airways
Describe how airway radius changes disproportionately affect airflow in infants and children
Apply Hagen–Poiseuille, LaPlace, Bernoulli, and Venturi principles to clinical airway management
Compare the effects of spontaneous breathing versus controlled ventilation in airway obstruction
Use physiologic reasoning to guide safer interventions for stridor and respiratory distress
